Starters - DELCO-REMY: Description
Starting motors are all 12 volt units with enclosed solenoid, shift lever and overrunning clutch. Starting motor circuits are different, depending on load and speed requirements. Five sizes of starter motors are used, 5MT, 10MT, 20MT, 25MT and 27MT. The only difference between the 10MT and the 20MT, 25MT and 27MT is the longer length of the latter 3 to incorporate an armature shaft center support bearing. The 5MT uses integral construction of field coils, pole shoes and frame.
